目的探讨新型及特殊口腔正畸保持器在口腔正畸治疗中的应用效果。方法选取2014年6月至2015年6月锦州市口腔医院收治的牙颌畸形矫治患者85例为研究对象,按不同的口腔正畸治疗方法分为观察组和对照组。观察组患者选择改良式热压模联冠透明器保持,对照组患者选择Hawley保持器保持。比较两组牙颌畸形矫治患者的上颌牙弓宽度及Little指数等。结果所有牙颌畸形矫治患者完成1年保持器的佩戴后,观察组患者上颌尖牙牙弓宽度、下颌尖牙牙弓宽度及磨牙牙弓宽度与对照组比较,差异均无统计学意义(均P>0.05)。观察组患者上颌牙Little指数及下颌牙Little指数明显低于对照组,差异均有统计学意义(均P<0.05)。结论针对牙颌畸形矫治患者,选择新型及特殊口腔正畸保持器可以显著提高患者的牙列固位效果,与Hawley保持器相比临床治疗效果更加显著,针对患者的牙列整齐度可以进行有效保持,最终显著提高牙颌畸形矫治患者的生命质量。
Objective To explore the application effects of orthodontics and orthodontics in orthodontic treatment. Methods Totally 85 patients with dento-maxillofacial deformity who were treated in Jinzhou Stomatological Hospital from June 2014 to June 2015 were selected as the research object. According to different orthodontic treatment methods, they were divided into observation group and control group. Patients in the observation group were selected to maintain a modified hot stamper in conjunction with a transparent caprolaluminium and control patients in the Hawley cage. The maxillary dental arch width and Little index of the two groups were compared. Results All patients with maxillofacial deformity underwent maxillary canine arch width, mandibular canine arch width and molar arch width compared with those of the control group after all 1-year orthodontic braces were worn. There was no significant difference (all P> 0.05). The maxillary tooth Little index and mandibular molar Little index in the observation group were significantly lower than those in the control group (all P <0.05). Conclusions For the treatment of dento-maxillofacial deformity, the selection of new and special orthodontic retainers can significantly improve the effect of dentition retention. Compared with the Hawley retainer, the effect of clinical treatment is more significant and the orthodontic treatment can be effective Maintain, and ultimately significantly improve the quality of life of patients with dental deformity correction.
